Furthermore, in some cases each eye can contribute to peripheral vision for one side of the field of view (see also monofixation syndrome). However, there is an exception to this: Those with true congenital alternating squints have two healthy eyes, and the ability to switch (by choice) between seeing with either eye.
When it comes to eye color, the melanin controlled by the OCA2 gene is diluted and thus we all have blue eyes. For those with that blue-eye gene mutation they eyes stay blue.
Some birds of prey, such as hawks, are believed to have an acuity of around 20/2; [33] in this respect, their vision is much better than human eyesight. When visual acuity is below the largest optotype on the chart, the reading distance is reduced until the patient can read it.
A new review reports that nine people taking semaglutide and tirzepatide — the active ingredient in GLP-1 medications — experienced vision issues, including three potentially blinding eye ...
